Failed to get location using opencellid.org Android
im using opencellid.org to get Mobile location from cell id, Mnc and Mmcc and other information, im getting CellId, MNC, MCC and LAC, but could not get location from this information. Error showing " android.os.NetworkOnMainThreadException "
Here is the code
public class OpenCellID {
String mcc; //Mobile Country Code
String mnc; //mobile network code
String cellid; //Cell ID
String lac; //Location Area Code
Boolean error;
String strURLSent;;
String GetOpenCellID_fullresult;;
String latitude;
String longitude;

return error;

If I'm not mistaken, I need to write an AsyncTask class, but I don't know what function or code should be written in the DoinBackground function in the AsyncTask class. Help would be appreciated
thanks in Advance

My class with async task looks like below
public class MainActivity extends AppCompatActivity {
private OpenCellID openCellID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
GsmCellLocation loc = (GsmCellLocation) tm.getCellLocation();
String networkOperator = tm.getNetworkOperator();
String mcc = networkOperator.substring(0, 3);
String mnc = networkOperator.substring(3);
int cellid = loc.getCid();
int lac = loc.getLac();
openCellID = new OpenCellID();
openCellID.setMcc(mcc);
openCellID.setMnc(mnc);
openCellID.setCallID(cellid);
openCellID.setCallLac(lac);
new GetLocation().execute();
}
class GetLocation extends AsyncTask<String, Void, Void> {
private Exception exception;
protected Void doInBackground(String... urls) {
try {
try {
openCellID.GetOpenCellID();
if(!openCellID.isError()) {
Toast.makeText(getApplicationContext(), openCellID.getLocation(), Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
} catch (Exception e) {
this.exception = e;
return null;
}
}
protected void onPostExecute(Void feed) {
// TODO: check this.exception
// TODO: do something with the feed
}
}
public class OpenCellID {
String mcc; //Mobile Country Code
String mnc; //mobile network code
String cellid; //Cell ID
String lac; //Location Area Code
Boolean error;
String strURLSent;
String GetOpenCellID_fullresult;
String latitude;
String longitude;
public Boolean isError(){
return error;
}
public void setMcc(String value){
mcc = value;
}
public void setMnc(String value){
mnc = value;
}
public void setCallID(int value){
cellid = String.valueOf(value);
}
public void setCallLac(int value){
lac = String.valueOf(value);
}
public String getLocation(){
return(latitude + " : " + longitude);
}
public void groupURLSent(){
strURLSent =

HttpResponse response = client.execute(request);
GetOpenCellID_fullresult = EntityUtils.toString(response.getEntity());
spliteResult();
}
private void spliteResult(){
if(GetOpenCellID_fullresult.equalsIgnoreCase("err")){
error = true;
}else{
error = false;
String[] tResult = GetOpenCellID_fullresult.split(",");
latitude = "23.028431";
longitude = "72.491422";
}
}
}
}
Another suggestion will add the api key to your url, otherwise it won't give you any result.
You can create api key from this link
Your url should be like this http://opencellid.org/cell/get?key=15e7c7be-4d6c-42bc-a79c-23be75abcc87&mcc=405&mnc=030&cellid=19757464&lac=30001&fmt=txt
